RewriteRule \.htaccess - [F]

RewriteCond %{THE_REQUEST} \?
RewriteRule .? http://www.example.com%{REQUEST_URI}? [R=301,L]

RewriteCond %{THE_REQUEST} /([a-z/-]+)\.
RewriteRule . http://www.example.com/%1 [R=301,L]

RewriteCond %{HTTP_HOST} .
RewriteCond %{HTTP_HOST} !^www\.example\.com$

RewriteRule .? - [G]

RewriteRule ^([a-z/-]+)?$ /script.php?url=$1 [L]

RewriteCond %{HTTP_USER_AGENT} ^User-Agent-Blocking [OR]
RewriteCond %{HTTP_USER_AGENT} Robot¦abot [NC]
RewriteRule .? - [G]

Just sort of a 'standard set' of rules I usually use to start new files.
